BOWLING-ALLEY.

SPECIFICATION forming part of Letters Patent No.490,916, dated January31, 1893.

lApplication tiled June 20, 1892.

To all whom 'it may concern:

Be it known that I, HENRY MONTGOMERY, a citizen of the United States,residing at Newark, county of Essex, and State of New Jersey, haveinvented certain new and,useful Improvements in Bowling-Alleys; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon,whichform a part of this specification.

The object of this invention is to provide a bowling alley, solid anddurable in construction and which will not sag, warp, or be affected bychanges of temperature.

The invention is an improvement on my patent No. 471,244, dated March22, 1892, and consists of the improved bowling alley and the arrangementand combination of the various parts thereof, substantially as will behereinafter more fully described, and finally embodied in the clauses ofthe claims.

Referring tothe accompanying drawings, in which like-letters ofreference indicate corresponding parts in each of the several figures.Figure 1. is a top plan view, with a portion broken away, to better showthe interior construction and arrangement of my improved bowling alley.Fig. 2. is a longitudinal sectional view on line w, Fig. 1. Fig. 3. is atransverse section on line z, Fig. 1, and Fig. 4. is an enlarged view ofthe rear end and pit of my alley, similar to the rear portion of Fig. 2.Y

In said drawings c, a, represent piersk or piles, arranged in the groundand adapted to support the longitudinal beams or sills b and also thecenter beams c, said center beams starting at about ve feet from thehome end of the alley and running parallel with the longitudinal beamsfor a distance of about twenty feet. The space between all said beamsmay be 'tilled in with concrete or any desired material. To the top ofsaid beams and parallel to each other are secured crossbars d, arrangedat different intervals. As

- clearly shown in Figs. 1 and 2, said crossbars are closer togetherunder that part of the surface, where the balls are apt to strike andSerial No.437124l. (No model.)

also at the rear end of the alley, where the falling pins are apt tocreate an additional strain. VThe space between said crossbars may befilled in with cement, ashes or any suitable material, or may be leftopen for the purpose of ventilation. To the top of said bars d issecured a oor e of Georgia pine or similar wood, on which again arearranged the doublebinders fof the alley, and the oors g and sides h ofthe gutters. Between the binders f, and on top of the pine iooring e maybe arranged a layer of felt rubber or other sound deadening material t'throughout the ent-ire length of the alley. Said felt or rubber beingadapted to act as a cushion for the surface lo of kthe alley proper.This surface k is by preference built up in four distinct sections m,fn, 0 and p as shown in Fig. 1. of the drawings.

The section m extending for about iive'feet at the home end of the alleymay be of Georgia pine and adjoins the section nwhich consists of aboutfifteen feet (in length) of maple. The third section o which is again ofGeorgia pine lls up the space between the second section n and thefourth section p, which latter is of maple and occupies about five feetat the rear end of the alley. These several sections are composed ofnarrow strips of their respective wood, which interlock with each other,that is to say, their joints are beveled in a longitudinal direction, asshown at q in Figs. 2 and 4. This form of beveling prevents the rippingor tearing of the surface, at the joints when being planed orsand-papered.

At the rear end of the alley is arranged the ordinary padded pit r,provided with an upwardly substantially circular extension s. Above thestarting point of said extension is pivotally supported the bumper t, towhich is secured the cushion u, substantially wedge shaped incross-section having its greatest thickness at the top. The curvedportion s and the specially constructed bumper t prevent the pins orballs from getting behind or jamming at the lower part of the saidbumper. As the balls have the tendency to rise on coming in contact withthe bumper, the wedge shaped cushion causes them to drop back in thepit.

IOO

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

l. In a bowling alley, piers or piles arranged in the ground at certainintervals, beams or sills arranged on said piers and extendinglongitudinally and parallel to each other throughout the alley, thespace between said i beams being filled up with concrete, crossbarssecured to said beams at certain intervals, a pine lioor arranged onsaid cross bars, double binders on each side of the alley, a layer offelt, rubber, or any suitable material between said binders and on saidfloor, and a series of narrow strips of wood arranged edge- Wise on saidfelt and adapted to form the surface for the alley, substantially asdescribed and for the purposes set forth.

2. In a bowling alley, piers or piles arranged in the ground, beams orsills arranged on said piers and extending .longitudinally and parallelto each other throughout the alley, center beams arranged between saidbeams and extending for acertain distance from or about from the homeend of the alley, the space between all said beams being lled up withconcrete, cross bars secured to said beams, and spaced narrower or wideras specified, a pine floor arranged on said crossbars, double binders oneah side of the alley, a layer of felt, rubber or any suitable materialbetween said binders and on said floor, and a series of nari row stripsof wood standing edgewise on said felt and adapted to form the surfacefor the alley, substantially as described and for the purposes setforth.

3. In a bowling alley, piers or piles arranged in the ground, beams orsills arranged on said piers and extending longitudinally and parallelto each other throughout the alley, center beams arranged between saidbeams and extending for a certain distance from or about from the homeend of the alley, the space between all said beams being tilled up withconcrete, cross bars secured to said beams, and spaced narrower or wideras specied, a pine floor arranged on said cross bars, double binders oneach side of the alley, a layer of felt, rubber, or any suitablematerial betweensaid binders and on said floor, and a series of narrowstrips of wood standing edgewise on said felt and arranged in foursections of Georgia pine and maple alternately, said sections beingadapted to form the surface for the alley,

substantially as described and for the puru poses set forth.

4. In a bowling alley, a pit provided with a curved extension, a bumperpivotally secured at the radial center of said curve and a cushionsecured to said bumper, said cushion having its greatest thickness atthe top, all said parts substantially as described and for the purposesset forth.

5. In a bowling alley, a pit having its rear wall bililt substantiallyin the form of an upwardly extending curve in combination with a bumperand cushion swung in bearings above the arc of said circular rear walland arranged so that the lower end of said swingi-ng bumper and cushionwill j ust clear the circular wall of the pit, substantially asdescribed.

6. In a bowling alley, a pit having a circular rear wall, in combinationwith a bumper and cushion swung in bearings arranged in the radialcenter of said circular wall and arranged so that their lower edge willjust clear the said wall of the pit, said cushion being substantiallywedge shaped in crosssection, the thickest portion being at the top ofsaid cushion, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this10th day of June, 1892.

HENRY MONTGOMERY.
